Application filed October 24, 1907. Serial No. 398,912.

T 0 all whom it may concern:

Be it known that I, JOHN J. KANE, a c1t1- zen of the United States, residing at Dover, in the county of Strafford, State of New Hampshire, have invented an Improvement in Insole-Reinforcing Machines, of wh ch the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to machines for applying reinforcing material to insoles for boots and shoes.

Heretofore it has been customary to employ three or more operations in reinforc ng insoles; first, a preliminary forming-1n by which the reinforce is crudely shaped by hand to the insole; next, an applying operation commonly performed by a machine, such for example as that shown in U. S. Patent No. 614,860; and finally, a following-up operation by which the reinforced sole is completed. It is an object of this invention inter alz'a to avoid the necessity for so many operations, as by combining the second and third in one; and also to provide means for shaping and forming the reinforced soleexpeditiously and accurately.

The invention may be described conveniently as embodied in a machine of the same type as that shown in the above mentioned patent.

In the drawings,-

Figure 1 is a side elevation of said machine, comparable to Fig. 2 of the patent aforesaid Fig. 2, a detail front elevation (viewed from the right in Fig. 1) of the parts of the machine which act upon the reinforce and insole;

Fig. 3, a transverse section of a reinforced insole illustrating a typical imperfection left by the operation of machines heretofore used;

Fig. 4, a transverse section of an insole, showing parts also disclosed in Figs. 1 and 2; and

Fig. 5, a transverse section of an insole,

showing it applied to a last preparatory to the inseam stitching operation.

The insole may rest upon a work support 6, suitably movable to accommodate the feed of the work. A presser 8 may act upon the upper face of the insole in opposition to the work support; and may be reciprocated conveniently to facilitate feeding the work by being mounted on a bell-crank l1 fulcrumed at 12 and rocked through its arm 13 by a cam 14. The latter is fixed upon a suitably supported shaft driven from abelt sheave 15. There may be also an anvil or former 16 and a bead forming tool 17 which may perform the double ofiice of a forming tool and a four-motion feeding device to cooperate with the movable'work support. To trim superfluous material from the edge of the reinforce the machine may have suitable trimming devices, such as the rotary disk cutters 19 and 20.

All of the devices referred to in the preceding paragraph may be exact counterparts of those disclosed in the patent aforesaid and may be operated in the same manner and by the same means. Obviously, therefore, reference may be had to said patent if the well-known construction and operation of said parts is not sufliciently understood.

In the illustrative machine embodying this invention the lip or bead of the insole stands between shaping and ironing tools 25 and 30. The tool 25 comprises a roller 26 appropriately mounted for rotation in a supporting shank bolted to the machine, by being journaled between two arms 27 and 28 (Fig. 4'.) the arm 27 lying between the roller and the lip or bead. It is thus seen that the shaping or ironing tool 25 is formed in two parts, one, the arm 27, which engages the side of the lip and another the roller 26 which acts in the angle between the lip and feather. The roller is arranged to press upon the reinforce overlying the insole feather, in order to iron them into secure adhesion. That side of the roller next to the bead is preferably beveled, together with the adjacent arm 27 of its supporting shank for purposes hereinafter explained.

On the opposite or inner side of the bead is the shaping or ironing tool 30, which in the exemplary form comprises afrustoconical roller, journaled on a vertical axis upon a shank bolted adjustably to the frame of the machine. The shaping and ironing tools 25 and 30 are relatively adjustable toward and from each other, as by providing the shank of the tool 30 with adjusting screws 31 and 32. This permits the tools to be moved horizontally toward or away from one another to accommodate insole beads of different thicknesses.

As illustrated in Fig. 4; the adjacent faces of the shaping and ironing tools 25 and 30 for engaging and pressing against the op 0- site sides of the lip or bead are prefera ly substantially parallel and so inclined as to bend the insole bead inwardly toward the face of the sole.

In the operation of the above described specific machine the bead is placed between the ironing and forming tools 25 and 30, and the tools and sole relatively move to permit the former to act on the latter along the length of the bead, as for example by having the sole fed past the tools in the manner and by the means described in said patent and shown in Fig. 1. Preferably the reinforce is to some extent laid over the bead and onto the feather before being introduced to the action of the shaping and ironing tools 25 and 30 and this may be conveniently effected by the bead forming tool and the anvil or former hereinbefore referred to, which may be constructed and may operate .as described in said patent. When the reinforce and sole are acted upon by the shaping and ironing tools 25 and 30, said tools engage the insole lip, then covered with the reinforce, and press the latter against the opposite sides of the lip. Preferably the tool 30 has at its lower end an acutely angu- Iar part arranged to enter completely into the extreme vertex of the angle formed between the bead and the face of the sole. Thus, said tool crowds or tucks the reinforce completely into said angle. Also, said tool by entering said angle may serve to lift up the lip, if the latter be bent over, in order to apply the reinforce properly to the inner face of the insole lip.

Fig. 3 shows in transverse section a reinforced sole presenting typical defects likely to remain after the sole has been reinforced by the machine of said patent and similar machines which do not possess the advantageous features of construction contemplated by this invention. It will be noted in Fig. 3 that the insole lip is bent or depressed and in consequence the reinforce, instead of being tucked properly into the inner angle of'the lip, is for a considerable space entirely unattached either to the lip or the body of the insole. This is a serious defect since when the needle which makes the inseam enters the unattached portion of the reinforce, it is likely seriously to tear it. Also, the needle and its stitch, by tending to draw the reinforce snugly into the lip angle, may either tear the reinforce or overcome its adhesion to the sole and further detach it.

Devices embodying the present invention, however, cure the defects just referred to by manipulating the lip so as to permit proper access to the inner angle which it forms with the face of the sole and by properly applying the reinforce to the sides of said angle. A typical product of a. machine'embodying this invention is well illustrated in Fig. 5, which in comparison with Fig. 3 clearly demonstrates its superior efficiency.

The forming and ironing tool 25 may also contribute to the above explained ob jects by assisting to iron the lip flat, instead of permitting it to be bent as in Fig. 3. The beveled arm 27 supports the outer side of the lip and presses the lip against the circumferential face of the roller 30, while the angular edge of the roller 26 acts in the angle formed by the intersection of the lip and feather, so as to tuck or press the reinforce into said angle, while at the same time pressing it against the lower portion of the side of the lip and the feather. WVith this construction the lip is bent inward by reason of its engagement between the inclined faces of the tools 27 and 30, and the reinforcing material is tucked into the angle of the lip and feather by the tool 26 which is mounted so as to be movable relatively to the lip bending tools in order to prevent a rupture of the reinforcing material where it may be loose in the angle, which fault is found to occur if a fixed, drag tool is employed at this point.

The opposed action of the specific tools 25 and 30 may serve to press the reinforce snugly against opposite sides of the lip throughout its entire extent from the extreme base of the lip immediately adjacent the face and feather of the sole up to the crown of the lip. The adjustment already referred to by which the tools 25 and 30 may be moved relatively toward or away from each other, permits the tools to be positioned properly for engaging lips or beads of any thickness.

Thebending over or collapsing of the insole lip represented in Fig. 3, is of very common occurrence, and nearly always the lip is bent inwardly. It is preferred, therefore, that the tool 30 or its equivalent have a species of plow-like action sufficient to lift or turn the lip upwardly and straighten it. The specifically illustrated form of frusto-conical roller performs this ofiice very effectively and at the same time may iron the lip out after it has been straightened.

When the above described operations take place the cement or other adhesive by which the sole and reinforce are held together, is preferably in a green state,that is to say, it is softened either by heat or moisture. The operation of the entire machine may act upon green cement and the parts, while freely pliable, may be tucked and ironed to the best advantage. When the several operations heretofore employed have been necessary, the later operations, as for example,

the following-up operation hereinbefore referred to, have acted upon the reinforce and insole after the cement had dried. Ob viously, this was a decided disadvantage. For example, the sole shown in Fig. 3, being ready for the following-up operation and the cement being dried, the reinforce was securely cemented to the middle of the sole face and also securely cemented to the feather. If, under these circumstances, a tool were pressed upon the reinforce in an attempt to tuck it into the angle of the lip, one of two disastrous results must necessarily follow: Either the reinforce would be torn, or would be at some point or other detached from the sole. This is avoided by the operation contemplated by this invention, wherein the application of the reinforce is entirely completed when the adhesive is in condition to permit free movement of the reinforce until finally shaped, whereupon the adhesive may be permitted to harden and dry.

Referring now to Fig. 4, the construction of the tools 25 and 30 shown for illustration, is such that the bead is inclined inwardly toward the middle of the sole so as to present an acute inner angle. While this result is by no means indispensable, it has considerable advantage. WVhen the sole shown in Fig. 3 has been passed throughafollowing-up machine, the latter will have so shaped the bead that it will stand substantially perpendicular to the face of the sole. Thereafter, when the sole is bent over a last convex in cross section the bead will be turned outwardly, presenting an acute angle with the feather and an obtuse angle with the face of the sole. Thus when the upper and linings are lasted they must be crowded into the acute feather angle of the bead or else in the process the bead will have to be manipulated so as to increase the angle. When, however, the result shown in Fig. 4. is produced, the subsequent fitting of the sole to the last as shown in Fig. 5, presents on the feather side of the bead an obtuse angle to receive the margins of the lasted upper and linings; and an acute angle upon the inner side of the bead, such that the channel guide can obtain a firm hold on the work and properly maintain it in position to re ceive the stitches through the bead at its base.

Various advantages other than those particularly pointed out are provided by this invention, as will appear to those familiar with the art of reinforcing insoles. One of the most considerable advantages resides in the provision for completing the application of the reinforce on a single machine, while the cement is green; and thereby avoiding successive operations some of which take place after the cement has dried more or less.

No attempt has been made to suggest or describe the various forms in which this in vention may be embodied, since as will appear to those skilled in the art a variety of different constructions and modes of operation may be employed in practising this invention without departing from the proper scope thereof. It is not essential that all the features of the invention be. employed conjointly, since they are susceptible of separate use to advantage.
